Function and Control
3.8
Fan Control
Outline
Fan control is carried out according to the following conditions.
1. Fan ON control for electric component cooling fan
2. Fan control when defrosting
3. Fan OFF delay when stopped
4. Fan control for maintaining pressure difference
5. Fan control when the compressor starts for heating
6. Fan control in forced operation
7. Fan control in POWERFUL mode
8. Fan control in low noise operation
9. Fan control in quiet mode
Detail
Fan OFF Control when Stopped
Fan OFF delay for 60 seconds must be made when the compressor is stopped.
3.9
Liquid Compression Protection Function 2
Outline
In order to obtain the dependability of the compressor, the compressor must be stopped
according to the conditions of the temperature of the outdoor air and outdoor heat exchanger.
Detail
Operation stop depending on the outdoor air temperature
Compressor operation turns OFF under the conditions that the system is in cooling operation
and outdoor air temperature is below –10°C.
3.10
Defrost Control
Outline
Defrosting is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor
heat exchanger temperature must be more than its fixed value when finishing.
Detail
Conditions for Starting Defrost
The starting conditions must be made with the outdoor air temperature and heat exchanger
temperature. Under the conditions that the system is in heating operation, 6 minutes after the
compressor is started and more than 28 minutes of accumulated time pass since the start of the
operation or ending the defrosting.
Conditions for Canceling Defrost
The judgment must be made with heat exchanger temperature. (4°C-22°C)
